1. Interactions between Streptococcus pyogenes and the human immune defence
Sammanfattning : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

2. Identification of Arthritis Susceptibility Genes in Mice and Humans
Sammanfattning : Rheumatoid arthritis (RA) is a chronic autoimmune disease with a largely unknown aetiology. The risk of developing RA is partly dependent on genetic factors, which has motivated extensive efforts to identify the disease regulating genes as away to understand disease pathogenesis. LÄS MER
3. Quantification of gene expression in single cells
Sammanfattning : Studies of apparently homogeneous cell populations and single cells often give highly divergent results. Cells exhibit varying responsiveness to stimuli and gene expression and they are in many aspects stochastic and unpredictable. We have developed a method to measure gene expression quantitatively in individual cells with real-time RT-PCR. LÄS MER
4. Involvement of eicosanoid signalling in epithelial cell migration
Sammanfattning : The development of inflammatory bowel diseases (IBD) and colon cancer (CC) has been shown to involve the up-regulation of inflammatory mediators and the machinery producing them such as the eicosanoids. Changes in the expression of extracellular matrix proteins and their related integrin receptors have also been shown to be important in the advancement IBD and CC. LÄS MER
5. Creation of a Nanometer-Scale Toolbox for Molecular Motor Transport-Circuits
Sammanfattning : This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. LÄS MER
